4.7.2 POWER MANAGEMENT

This system provides baseline hardware support of ACPI- and APM-compliant firmware and software. Key power-consuming components (processor, chipset, I/O controller, and fan) can be placed into a reduced power mode either automatically or by user control. The system can then be brought back up (“wake-up”) by events defined by the ACPI specification. The ACPI wake-up events supported by this system are listed as follows:

ACPI Wake-Up Event	System Wakes From
Power Button	Suspend or soft-off
RTC Alarm	Suspend or soft-off
Wake On LAN (w/NIC)	Suspend or soft-off
PME	Suspend or soft-off
USB	Suspend only
Keyboard	Suspend only
Mouse	Suspend only

4.7.3 SYSTEM STATUS

These systems provide a visual indication of system boot and ROM flash status through the keyboard LEDs and operational status using bi-colored power and hard drive activity LEDs as indicated in Tables 4-12 and 4-13 respectively.

NOTE: The LED indications listed in Table 4-13 are valid only for PS/2-type keyboards. A USB keyboard will not provide LED status for the listed events, although audible (beep) indications will occur.
